Halite, commonly known as rock salt, commonly found and well known mineral, the mineral form of sodium chloride.  Halite forms isometric crystals. The mineral is typically colorless or white, but may also be light blue, dark blue, purple, pink, red, orange, yellow or gray depending on the amount and type of impurities.  It can be found in salt lakes and oceans in a dissolved solution or as a solid mass in various locations formed via various processes.  It commonly occurs with other evaporite deposit minerals such as several of the sulfates, halides, and borates.  Pink halite is regarded as a crystal of personal power and healing.

Tourmaline is one of the most chemically complicated of all Silicate minerals.  It is a complex Silicate of Aluminum and Boron and the composition varies widely with Sodium, Calcium, Iron, Magnesium, Lithium and many other elements that enter into it's structure.  It can occur in a long, slender needle-like crystal to a thick prismatic and columnar crystal to a radial like daisy formation.  It comes in many colors usually black and brown (iron rich); brown and yellow (magnesium rich); and blue, red, green, yellow, and pink (lithium rich).  This mineral is found in igneous rocks, like Granite Pegmatite, and metamorphic rocks such as Schist and Marble.

Pyrite, or Iron Pyrite, is an Iron sulfide with isometric Crystals that usually appear as cubes.  It is brittle and can break or powder easily.  Its metallic luster and brass yellow hue have earned it the nickname of "fool's gold" due to many miners mistaken it for the real thing.  Ironically, small quantities of actual gold are sometimes found in Pyrite.  It is the most common of the sulfide minerals and is usually found with other sulfides or oxides in Quartz veins, sedimentary or metamorphic rocks.

Fluorite, also referred to as fluor-spar, is a mineral composed of Calcium Fluoride.  It is a widely occurring mineral found world wide and is often found with metallic minerals such as Galena, Sphalerite, Barite, Quartz and Calcite.  Fluorite may fluoresce strongly in ultraviolet light which may be due to the presence of some impurities such as Yttrium.  Blue is the most common color but red, purple, green, yellow and white are also frequent.  It can be used in high performance telescopes, camera lens, enamels and in the making of opalescent glass.

Prehnite is a semitransparent to translucent mineral with a chemical formula of calcium and aluminum.  It normally ranges in color from yellow-green to apple green.  Prehnite is a very hard mineral ranging from 6 to 6.5 on the Mohs scale  It is in the orthorombic crystal class usually found in radiating botryoidal (grape like) forms. It frequently occurs with epidote and quartz minerals.

Epidote is an abundant rock-forming mineral, but one of the secondary origin. Many of the characters of the mineral vary with the amount of iron present. Prismatic, columnar crystals, often shiny, finely striated faces. The color is green, gray, brown or nearly black but usually a characteristic shade of yellowish-green or pistachio green.

Calcite is a Carbonate mineral that is most widely distributed on the Earth's surface.  It is a common constituent of sedimentary rocks with Limestone in particular.  A Calcite formation can take on many different shapes and sizes which is dependent on the location, ground water occurrence and temperature.  Calcite is usually white or colorless but can be gray, red, yellow, green, blue, violet, brown or black.  The deeper the color is usually indicative of the definitive impurities from the earth or water.

Scolecite is a hydrated calcium silicate mineral belonging to the Zeolite group. It commonly occurs as sprays of thin, prismatic needles, frequently flattened on one side. Scolecite is usually colorless or white, but can also be pink, salmon, red or green. It is transparent to translucent, with a white streak and a luster which is vitreous, or silky for fibrous specimens. Scolecite is a common Zeolite often found with associated minerals including quartz, apophyllite and stilbite.

Stilbite is another Silicate mineral from the Zeolite family. It is often characterized by its sheaf like aggregates. The color is usually white or pink and when the cleavage is perfect, will have a distinct pearly luster.

Quartz is the second most common mineral in the Earth's continental crust.  It is mainly composed of Silica or Silica based minerals.  Although Quartz is known by a variety of names, the most important distinction between types of Quartz is that of macro-crystalline, individual crystals visible to the unaided eye, and micro-crystalline, where aggregates of crystals are only visible under high magnification.  There are many forms of Quartz including Chalcedony, Amethyst, Citrine, and Carnelian which are results of mineral impurities or heat treatments.

Crocoite is a mineral consisting of lead chromate that fascinates collectors.  First found in Russia and other European localities, but only sparingly and with very small crystals. The Australian discovery on the island of Tasmania took this mineral to a totally different level whit large brilliant, well formed crystals and far more abundant.  Crocoite is commonly found as large, well-developed prismatic crystals, although in many cases are poorly terminated.  Crystals are of a bright hyacinth-red color, translucent, and have an adamantine to vitreous luster.
